Add table reorder callbacks

[chosten]

Description

Since #6208 model events are not triggered anymore when reordering table records. It is a problem when using Laravel Scout for example.
This PR adds a before and after reorder callback.

Same as #15055 because I needed it again for 4.x.

Functional changes

• Code style has been fixed by running the composer cs command.
• Changes have been tested to not break existing functionality.
• Documentation is up-to-date.

I'd need help for the documentation if it is required. English is not my primary language.

Sample usage

$table->reorderable('sequence', afterReorder: function (array $order): void {
    Item::whereIn('id', $order)->get()->each->searchable();
});
